Alarms are a complete waste of time (I was in a car park the other day when one went off and the guard must be still reading that express) and in 2006 in Trinidad, I don't advise you run out to your car when your paging alarm goes off lest you find youself with more issues than a stolen car.
What a friend of mine did is welded an assortment of fish hooks on to a metal plate and puts it under the seat fabric at night... not dat is security
